Systems and methods for transferring a flexible conductor onto a moving web

ABSTRACT

A roller features a circumferential trench into which a wire is deposited from a wire dispensing head having a wire dispensing tip. A moving web of material engages the roller as the roller rotates. The wire dispensing tip engages sidewalls of the trench so that the wire dispensing tip remains in the trench as the roller rotates. Wire from the trench is deposited onto the web of moving material and is secured thereto by fasteners or tape or adhesive or the like.

CROSS-REFERENCE TO RELATED APPLICATION(S)

The present application claims priority to and the benefit of U.S. Provisional Patent Application No. 62/565,594 filed Sep. 29, 2017, which is incorporated herein by reference in its entirety.

BACKGROUND Field of the Disclosure

The present subject matter relates to antennas formed from flexible conductors and, more particularly, to systems and methods for transferring a flexible conductor onto a web of material for use in wireless communications technology.

Description of Related Art

Systems incorporating wireless communication technology, including Radio Frequency Identification (RFID) tags, are widely used for a variety of different applications, including inventory control, tracking, guarding and security systems. Such systems are well known in the retail industry, including use in connection with clothing inventory control and security from theft and other losses.

RFID tags may have a variety of integrated components, among them an RFID device or chip containing data such as an identification code for the type of product and/or product component and a unique identification code, allowing for immediate electronic identification and tracking of the exact item associated with the unique identification code. Other RFID tag components include an antenna electrically connected to the RFID chip or device, which is responsible for transmitting signals to and/or receiving signals from another RFID device or an RFID reader system.

RFID tags are often used on clothing, labels or other items or products made of fabric material (“fabric items”). A conductive wire or thread may be an efficient conductor for constructing an antenna, while also providing a degree of flexibility (particularly when having a circular cross section). In addition, depending on the material, such conductors may be deformed many times without fracturing or breakage. As a result, flexible conductors are desirable for use in forming antennas for RFID tags applied to fabric items. However, use of high pressures and temperatures during aggressive processes to securely attach flexible conductors to RFID devices and fabric items may result in damage to the fabrics.

DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS

As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriate manner.

Embodiments of the present disclosure provide systems and methods of dispensing wire into a shaped groove or trench in a roller to form the outline of an antenna and then depositing the antenna onto a moving web of material. As used herein, the term “wire” refers to any elongated, flexible conductor including, but not limited to, one or more cables, threads, wires or strands of electrically conductive material.

An embodiment of a system according to an aspect of the present disclosure is illustrated in FIG. 1. A wire dispenser includes a head 12. As illustrated in FIG. 2, the head 12 has a dispensing tip, indicated at 14. The head 12 receives a wire 18 a (FIG. 1) fed from a roll of the wire, illustrated in phantom at 22, or another supply source, and dispenses it through the dispensing tip 14, as indicated by arrow 16 of FIG. 2. As an example only, the wire dispensing tip 14 may be a conduit.

A roller 24 is rotationally mounted so as to rotate about a longitudinal axis, indicated in phantom at 26 in FIG. 1. The roller 24 has a continuous circumferential groove or trench 32 formed in the outer roller surface 34 of a defined width, depth and shape. The roller may be formed from steel or any other durable, rigid or semi-rigid material. While a wave-shaped trench 32 is illustrated, the trench may feature alternative shapes without departing from the scope of the present disclosure.

The wire dispenser head 12, or merely the dispensing tip 14, is mounted so that it is free to move generally in the directions of arrows 36 a and 36 b of FIGS. 1 and 2 (i.e., in direction parallel to the rotational axis 26), while preferably remaining in a generally fixed vertical position. As an example only, the wire dispenser head may be mounted in an overhead bracket or rack. The wire dispenser tip 14 may be mounted on a compliant material such as rubber where the force applied by the edges of the trench will distort it in the direction indicated. It should be noted that the amount of deflection obtainable by this simple form of mount is limited as the angle of the dispenser tip 14 engaged into the trench 32 changes with deflection. Alternatively, the dispenser 12 may be mounted on a linear track with a defined resistance to cross web motion, for example a linear track with the dispenser moving on a ball bearing. The defined resistance may also include a degree of damping to prevent unwanted oscillations of the dispenser position induced by the cross web motion. Alternatively, the cross web motion may be driven using an element such as an electrical linear actuator or air driven cylinder. The motion of the cylinder is driven to keep the dispenser head 12 in the trench 32. In one embodiment, the linear actuator provides a coarse element of the motion where the fine motion is provided by the dispenser head 12 being engaged in the trench 32 as before. This may be particularly advantageous when combining two forms of mount, a linear actuator for coarse motion and the tip being mounted on rubber for fine motion, as the rubber will also damp the motion and prevent vibration.

As illustrated in FIG. 2, the dispensing tip 14 of the wire dispenser head is positioned within the trench 32. As a result, the dispensing tip 14 is engaged by the sidewalls 38 a and 38 b of the trench 32 as the roller 24 (FIG. 1) rotates about the axis 26 in the direction of arrow 42. The resulting alignment forces, illustrated by arrows 40 a and 40 b in FIG. 2, cause the wire dispenser head 12 to move in the general direction of arrows 36 a and 36 b as the dispensing tip 14 traverses the trench 32, similar to the manner in which a needle follows the groove of a phonograph record. As a result, a self-guided wire dispenser is formed.

As illustrated in FIG. 1, a web of material 44 passes under, and engages the bottom of, the roller 24, and travels in the direction of arrow 46. As an example only, the directions of arrows 36 a and 36 b may be generally perpendicular to the direction of travel 46 of the web of material 44. As is known in the art, the web 44 is moved at a speed equal to the rotational velocity of the roller 24, which may have its own rotational drive system. As examples only, the web of material 44 may be fabric, paper or plastic. Suitable systems for moving or driving the web in the manner illustrated in FIG. 1 are known in the art and, as an example only, may include a feed roll of the material, indicated at 45, and a take-up roll, indicated at 47, which features its own rotational drive system (such systems being known in the art and generally understood in web handling technology).

As illustrated in FIG. 1, the roller 24 contacts the moving web 44 at a location different from the position that the wire 18 a is dispensed into the trench 32 of the roller. While FIG. 1 illustrates the wire dispenser head 12 as being substantially diametrically opposed to the web of material 44 with respect to the roller 24 (i.e., spaced approximately 180° from the web of material 44 about the roller 24), it should be understood that the wire dispenser head 12 and the web of material 44 may be separated by some other angle about the roller 24 without departing from the scope of the present disclosure.

As the wire exits the dispensing tip 14 of the wire dispenser, it is deposited within the trench 32 of the roller. As a result, the wire takes on the shape of the trench. The wire 18 a is dispensed at a rate consistent with the rotational velocity of the roller so that the wire is continuously deposited in the trench. The trench 32 is provided with an arrangement for securing the wire therein. The wire remains in the trench 32 until it comes into contact with the moving web 44 and is transferred thereto, while retaining the shape of the trench (wave-shaped in the embodiment of FIG. 1), as illustrated at 18 b in FIG. 1. The transferred wire is attached to the web by methods such as adhesives or mechanical fasteners such as staples or stitches, by other bonding methods, ultrasonic welding and as will be described in greater detail herein.

An arrangement for securing the wire 18 a within the trench 32 is provided in configurations where gravity could otherwise pull the wire out of the trench 32 before it is transferred to the web 44. Such an arrangement could include, for example, the provision of an adhesive in the trench (illustrated in phantom at 48 in FIG. 2) or a vacuum in the trench via ports (illustrated in phantom at 52 in FIG. 2) that are in fluid communication with a suction source. Other suitable securing arrangements may alternatively be used without departing from the scope of the present disclosure.

The positioning of the wire dispenser head 12 (i.e. the “dispense position”) with respect to the moving web of material 44 may be varied from what is illustrated in FIG. 1 with respect to the roller 24, as noted above. For example, in FIG. 3A, when the web 44 is below the roller, with examples of possible dispense positions being illustrated at 12 a, 12 b and 12 c. The distance around the roller from the dispense position can vary the amount of room available for other processes, such as attaching a chip to the wire. In cases 12 a, 12 b and 12 c, the roller 24 must incorporate some arrangement for retaining the wire in the trench (described above with reference to FIG. 2) to prevent it from being pulled out by gravity before transfer to the web 44.

As illustrated in FIG. 3B, the web 44 a may alternatively run above the roller 24 a, with examples of possible dispense positions being shown as 12 d, 12 e and 12 f. Position 12 d, as it is above the roller 24 a, can have the wire captive in the trench of the r36aoller by gravity, rather than requiring an additional arrangement for retaining the wire in the trench.

It should be understood that the positions illustrated in FIGS. 1, 3A and 3B are merely exemplary, and that positions other than those illustrated in FIGS. 1, 3A and 3B may alternatively be used for the dispense position and moving web position.

An alternative embodiment illustrated in FIG. 4 includes an arrangement where an adhesive is screened into the roller trench either before or after the wire is inserted. More specifically, a web of material 44 a travels in the direction of arrow 46 a and passes between, and is engaged by, roller 24 a and a pinch roll 60, which are rotating in the directions of arrows 42 and 62, respectively. The roller 24 a features a circumferential trench, such as trench 32 of FIG. 1. A trough 64 contains an adhesive 66, and the bottom portion of the roller 24 a is submerged in the adhesive. As the trench of roller 24 a passes through the adhesive 66, the adhesive fills (or partially fills) the trench. Excess adhesive is removed with a doctor or scraping blade 68. Wire from dispensing head 12 g is deposited in the trench in the manner described above with respect to FIGS. 1 and 2, and is fully or partially submerged within the adhesive therein. The wire in the trench then travels to the nip point 72 and is transferred to the web of material 44 a. The adhesive permits the wire to stick to the web when it is transferred thereto.

Types of adhesives 66 may include pressure sensitive, hot melt, ultraviolet curable and others. The placement of the adhesive into the trench can be screened but also delivered by other means, for example jetted in or extruded along with wire.

In an embodiment according to another aspect of the present disclosure, which is illustrated in FIGS. 5-7, a tape 74 is inserted into the trench of the roller 24 a before or after the wire 18 d. More specifically, a web of material 44 a travels in the direction of arrow 46 a and passes over, and is engaged by, roller 24 a, which is rotating in the direction of arrow 42. The roller 24 a features a circumferential trench, illustrated at 32 a in FIG. 6. An adhesive tape 74 is deposited in the trench of the roller 24 a, with a sticky side (76 in FIG. 6) facing radially outwards, using a tape dispenser head. The tape can be a double sided tape such that there is adhesive on both sides to secure the tape to the web in the trench and the wire to the tape. The tape dispenser head is movably mounted in the same manner as illustrated for wire dispenser head 12 in FIG. 1 and has a dispensing tip 14 positioned in the trench of the roller 24 a in a manner similar to dispensing tip 14 of the wire dispenser head of FIG. 2. As a result, the tape dispensing tip stays within the trench 32 a as the roller 24 a rotates. Wire 18 d from a dispensing head is deposited in the trench in the manner described above with respect to FIGS. 1 and 2. As a result, the wire 18 d is placed on top of the sticky side 76 of the adhesive tape 74 in the trench 32 a, as illustrated in FIG. 6.

Once deposited within the trench 32 a of the roller 24 a, the wire 18 d and tape 74 are transferred to the web 44 a and secured in place, as illustrated in FIG. 7. As a result, the wire 18 d is secured to the web 44 a via the tape 74. When a pressure sensitive adhesive is used on the tape 74, a pinch roll, indicated in phantom at 78 in FIG. 5, may be required to provide a nip, but other adhesives, as well as the pressure sensitive adhesive, may require heat in the form of heated rollers. If the trench is coated with a non-stick material such as polytetrafluoroethylene (PTFE), the wire and adhesive may be heated in the trench prior to transfer to the web.

As an example only, the tape may be a continuous strip of an adhesive, such as a hot melt or a thermoplastic polyurethane, that combines strength and adhesive properties on a surface such as fabric, or a composite of a fabric and an adhesive, which gives a high strength bonding the wire to the web surface.

In alternative embodiments, the tape 74 of FIGS. 5 and 6 may include sticky surfaces on both sides to aid in retaining the tape and wire within the trench 32 a of the roller 24 a, or in embodiments where the wire is deposited within the trench prior to the tape.

In an embodiment of the disclosure shown in FIGS. 8-10B, before the wire is placed in the trench of the roller 24 a, a fastener strip 80 (FIG. 8) for securing the wire to the web of material 44 a is inserted. The fastener strip, with reference to FIGS. 9-10B features a number of fastener or staple portions, indicated in general at 82, which are shown as each having a U shaped profile terminating in pointed ends 84 a and 84 b, although it should be understood that the fastener portions may be variously configured without departing from the scope of the present disclosure. The fastener strip may further include a backbone, illustrated in phantom at 86 in FIG. 9, securing the fastener portions 82 together. The fastener strip is preferably formed from plastic, or other soft, flexible material but other materials may be used.

With reference to FIG. 8, a web of material 44 a travels in the direction of arrow 46 a and passes between, and is engaged by, roller 24 a and a pinch roll 60, which are rotating in the directions of arrows 42 and 62, respectively. The roller 24 a features a circumferential trench, such as trench 32 of FIG. 1.

The fastener strip 80 is deposited in the trench of the roller 24 a, with the pointed ends 84 a and 84 b of the fastener portions 82 pointing radially outwards from the rotational axis of the roller 24 a, using a fastener dispenser head. The fastener dispenser head is movably mounted in the same manner as illustrated for wire dispenser head 12 in FIG. 1 and has a dispensing tip positioned in the trench of the roller 24 a in a manner similar to dispensing tip 14 of the wire dispenser head of FIG. 2. As a result, the fastener dispensing tip stays within the trench of the roller 24 a as the roller rotates. Wire 18 e (FIG. 9) from a dispensing head 12 h (FIG. 8) is deposited in the trench of the roller 24 a in the manner described above with respect to FIGS. 1 and 2. As a result, the wire 18 e is placed on top of the fastener portions 82 and spine 86 of the fastener strip 80 in the manner illustrated in FIG. 9.

Once deposited within the trench of the roller 24 a, the wire 18 e and fastener strip 80 are transferred to the web 44 a and secured in place. More specifically, when the wire and fastener strip are applied to the web 44 a, the points 84 a and 84 b of the fastener portions 82 of the fastener strip penetrate the web material, as illustrated in FIG. 10A, and are then turned inward by the pinch roll (60 of FIG. 8), as illustrated in FIG. 10B, forming a mechanical connection similar to staples mechanically securing the wire to the fabric, as illustrated in FIGS. 8 and 10B.

Rather than a continuous fastener strip 80, discrete fastener portions or sections of plastic staples can be placed in the trench of the roller 24 a to minimize the amount of plastic which may stiffen the web. An adhesive may be added at any of the above stages to better secure the wire and fastener structure.

Methods of connecting a Radio Frequency Identification (RFID) device, or other electronic device, to a wire prior to transfer of the resulting RFID tag to a moving web of material using systems according to the present disclosure are illustrated in FIGS. 11A and 11B.

In FIG. 11A, a circumferential trench is formed in a roller, similar to trench 32 and roller 24 of FIGS. 1 and 2, so that a wire, indicated in general at 18 g in FIG. 11A, deposited in the trench is formed with loops 90. As further illustrated in FIG. 11A, an electronic device, such as RFID device 92 a, which may include electronic circuitry and, as examples only, can be an actual RFID device, a strap form or a bare die, is first positioned within the trench in a position so that the wire 18 g, when introduced into the trench, in the manner described above with reference to FIGS. 1-8, overlays the RFID device. The wire 18 g is then attached to the RFID device at contact points 94 a and 94 b to provide an antenna for the RFID device so that an RFID tag is formed, while the loop 90 provides a tuning inductance.

The RFID device 92 a and the assembled RFID tag may be secured in the roller trench by, as examples only, a vacuum or low tack adhesive (discussed previously with reference to FIG. 2). In addition, the trench of the roller may optionally be provided with dedicated recesses, an example of which is indicated in phantom at 98 a in FIG. 11A, configured to receive and hold a number of RFID devices 92 a as the wire 18 g is attached thereto and prior to transfer of the resulting RFID tags to a web of material.

The joints or connections between the wire 18 g and the RFID device 92 a at contact points 94 a and 94 b can be achieved in a number of ways known in the art. As examples only, a conductive adhesive, soldering, ultrasonic welding or electrical welding (or any other type of welding) may be used. In addition, a capacitive contact may be made by forming pads of the RFID devices over the wire with a non-conducting adhesive such as a pressure sensitive adhesive.

The contact between the RFID device and the wire can be achieved in a number of ways. The RFID device, e.g. strap based or bare die/chip, can be placed in an aperture in the trench before the wire is dispenser. The device may be coated with an adhesive, such as an isotropic conductive paste, which contains flakes of a conductor such as silver, an anisotropic adhesive, where a conductive paths is formed in a vertical direction when compressed and heated, of a non-conductive adhesive such as a PSA, where coupling between the wire and device is made by capacitance.

For soldering, a solder paste may be placed onto the device surface before the wire is placed in position. All of the above can be cured using pressure and, if needed, heat, applied by a pinch roller after the wire is dispensed. Alternatively, if the wire itself is heated, it may cause the joint to be formed when it is placed in contact with the bond pads of the device. For welding, a secondary tool may be used in the trench after the wire has been dispensed on top of the strap which applies such factors as ultrasonic energy, electrical energy or pressure to crimp the materials depending on what is required. It will be appreciated that similar methods may be used if the wire is dispensed into the trench before the strap is placed. Alternatively, the strap of other form of RFID device can be attached to the wire antenna when it has been transferred to the web of material as long as the web, such as fabric, is not damaged by the forces/heat used.

With reference to FIG. 11B, an RFID device 92 b may be used to bridge a gap in a wire having sections 18 h and 18 i to form a portion of an antenna. Similar to the method described with reference to FIG. 11A, the RFID device 92 b is initially positioned within the trench of the roller, and then a wire is introduced into the trench in the manner described above with reference to FIGS. 1-8 so as to overlay the RFID device. The RFID device 92 b and resulting RFID tag may be secured within the trench of the roller using the methods described with reference to FIG. 11A.

After introduction into the trench, the wire is cut to form sections 18 h and 18 i. The wire can be cut by a blade at the aperture of the dispenser or alternatively, pre-determined sections can be fed to the trench. Where the wire is being driven out into the trench and not pulled by adhesion of the tape or adhesive in the trench, the wire will dispense into the trench and will have a gap, which then are attached to the RFID device 92 b at contact points 94 c and 94 d using a method such as those described above with reference to FIG. 11A. Alternatively, the wire may be attached to the RFID device 92 b at contact points 94 c and 94 d and then cut between the contact points by a blade or rotary cutter engaged into the slot that can be moved down to make a cut at a specific point so that wire sections 18 h and 18 i are formed. In yet another embodiment, the wire may be cut to form sections 18 h and 18 i prior to introduction into the trench.

As in the case of FIG. 11A, the trench of the roller may optionally be provided with dedicated recesses, an example of which is indicated in phantom at 98 b in FIG. 11B, configured to receive and hold a number of the RFID devices 92 a as the wire is attached thereto and prior to transfer of the RFID tag to a web of material.

The RFID tags produced using the methods of FIGS. 11A and 11B are attached to a web of material that may be positioned above the roller (examples provided in FIGS. 3B, 4, 5 and 8) or below the roller (examples provided in FIGS. 1 and 3A). The system may also include a pinch roll (such as pinch roll 60 of FIGS. 4 and 8) to provide a nip point to provide a force to transfer the wire and secure it in place on the RFID device.

Examples of advantages of the technology of the present disclosure may be observed where the RFID tags of FIGS. 11A and 11B are transferred onto a material such as a fabric for use in making care labels for clothing or other branding labels, e.g. woven labels which appear inside a garment or as an external embellishment of the brand or other logo.

The fabrics of such labels are typically soft fabrics that are not generally robust against high temperatures and pressures, and may be damaged if the RFID device and wire were instead applied to the fabric separately and then joined at the contact points. If the RFID device and wire are in the trench of the roller, as described above for FIGS. 11A and 11B, the connection can be made while avoiding damage to the fabric. More specifically, in a roller formed of a durable material such as steel, another steel tool can apply high pressures against it, useful in welding of all forms to hold the metals together. In addition, such a roller provides a solid surface with controlled thermal properties more suitable for the process of forming the connection point joints or connections.

Temperatures to cure conductive adhesives can exceed 150° C., and may need to be applied for a number of seconds. If the roller itself is heated, and an adhesive is jetted into the connection points between the wire and the RFID device, the required curing time can be achieved by properly choosing the roller diameter and rotation speed of the roller.

Furthermore, for ultrasonic welding, the joints or connections at the contact points (94 a and 94 b in FIG. 11A or 94 c and 94 d in FIG. 11B) are best made against a solid surface, such as the surface of the roller, as soft materials dissipate the ultrasonic energy.

The embodiments described above with reference to FIGS. 11A and 11B therefore provide a method of connecting an RFID device to a wire that is particularly effective, as the wire and device are embedded at the time of connection in the trench of the roller, where the latter is preferably constructed of a robust material, such as steel. The roller provides a stable base for connecting the RFID device to the wire using relatively high pressures and temperatures, which would damage a web of fabric or paper material if the connection were after transfer of the RFID device or wire to the material.

It will be understood that the embodiments described above are illustrative of some of the applications of the principles of the present subject matter. Numerous modifications may be made by those skilled in the art without departing from the spirit and scope of the claimed subject matter, including those combinations of features that are individually disclosed or claimed herein.
